Question type: Slider

I propose a new question type: Slider.

It is quite often the case that you would ask for answers that have a fixed order. That could be a rating based on 0-5 Stars or asking for a number. If I use radio buttons, the options are ordered by the numbers of answers in the results, which doesn't make sense.

As it would be an option, to make an extension to the radio-buttons to set the options order as "fixed", it seems more convenient to generate a whole new question type of "ordered options", which can be selected with a slider. This also increases the gamification, hopefully generating higher return rates, i.e. when used for evaluations.

The answers could be numbers (in the easiest case), start, end and interval could be selectable. Otherwise distinct values or icons (i.e. stars) could be put in by the creator, but would be interpreted as numbered answers to calculate the results. The options could be all printed out to the user or only the extremes and the current selected one are shown. Probably this would be dependent to screen sizes and number of options.

The results could be simply drawn as bars like from questions with radio-buttons (in fixed order instead of the frequency), but also the mean value and deviation could be calculated. Distribution graphs are another (yet inaccurate) option.

Problems might occur regarding unanswered questions. The slider has to start on one value to be accessible by the user, but this might lead to an unwanted answer being filed in. A solution could be a distinct value "no answer".

I will probably add this type on my own when I find the time. But I wouldn't be angry at all, if somebody else is faster.
